Hola amigos del GIS, Por motivos de trabajo que no vienen al caso, he tenido que bucear de manera sistemática la web de descargas del CNIG. http://centrodedescargas.cnig.es/CentroDescargas/inicio.do Una maravilla. Por motivos que tampoco viene al caso, he de hacer esto mismo de vez en cuando en todos los Institutos cartográficos del mundo y el delContinue reading “Descargas del CNIG. Open Source bien hecho!”
Hi guys, Surfing the internet is great when you need to figure out something. I needed to validate some DTM from unknown sources against an also unknown source (but at least a kind of reliable one, Google Earth). All we need is Google Earth TCX converter ARcGIS Excel This is the procedure i have followed:Continue reading “DTM validation using Google Earth (and RMSE extraction)”

I’ve already entered my river but my imagery was in 2D so… was it well acquired?… First of all, I import my shape (shp) file into Global Mapper (what a great sofware!) and export my vector file as a KML. Import my river.kml file into my brand new Google Earth 5.2 or just double-click itContinue reading “Data acquisition: How do I know if this river is been well acquired?”
Even from scratch or from dgn/dxf vectorial format’s contour lines you create your own scenario. Then import your model previously created using Sketch-up (this time i used google’s 3d warehouse, thank you Dilbert). Stamp your house using sketch-up sandbox tools. Then fur your scenario as if it was grass… A little of photoshop like clouds andContinue reading “GIS+Architectural scenaries. Awesome!”

I used to have lunch every thrusday there, at the ‘Restaurante Asiático SHENG’. I strongly recommend you ‘entremeses’ (In China you will find them as ‘dim-sum’) and Cantonese duck or Hong Kong duck (this was slightly spicy thou). Very good food, very fast service and pretty cheap menu: 10,7 €… ideal for an IT worker!. TheseContinue reading “One more 3D building. Avenida de la Vega 28108. Restaurante Asiático SHENG.

Navigating all over the world within Google Earth I have just discovered a brand new 3d layer in Helsinki, Finland. Almost every building around makes this scenario very realistic… You just have to click on ‘3d buildings’ and it will show you this incredible layer… Does anybody know a WMS map to use it here?.Continue reading “News: Amazing Helsinki 3D!”
And Now I would like to add one more set of buildings around my house. This is a block of flats in Vicálvaro, Madrid, Spain. This is supposed to be ‘Valderribas’ area… hope you like them!
First of all, what is KML?. KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays, and expose rich data in new ways. KML is an international standard maintained byContinue reading “Creating and personalizing KML code (placemarks).”
